public EObjectDescriptionContentProvider()

Method Detail

dispose

public void dispose()

Description copied from interface: org.eclipse.jface.viewers.IContentProvider

Disposes of this content provider. This is called by the viewer when it is disposed.

The viewer should not be updated during this call, as it is in the process of being disposed.

Specified by:

dispose in interface org.eclipse.jface.viewers.IContentProvider

inputChanged

public void inputChanged(org.eclipse.jface.viewers.Viewer viewer,
                         java.lang.Object oldInput,
                         java.lang.Object newInput)

Description copied from interface: org.eclipse.jface.viewers.IContentProvider

Notifies this content provider that the given viewer's input has been switched to a different element.

A typical use for this method is registering the content provider as a listener to changes on the new input (using model-specific means), and deregistering the viewer from the old input. In response to these change notifications, the content provider should update the viewer (see the add, remove, update and refresh methods on the viewers).

The viewer should not be updated during this call, as it might be in the process of being disposed.

Specified by:

inputChanged in interface org.eclipse.jface.viewers.IContentProvider

Parameters:

viewer - the viewer

oldInput - the old input element, or null if the viewer did not previously have an input

newInput - the new input element, or null if the viewer does not have an input

updateElement

public void updateElement(int index)

Description copied from interface: org.eclipse.jface.viewers.ILazyContentProvider

Called when a previously-blank item becomes visible in the TableViewer. If the content provider knows the element at this row, it should respond by calling TableViewer#replace(Object, int). NOTE #updateElement(int index) can be used to determine selection values. TableViewer#replace(Object, int) is not called before returning from this method selections may have missing or stale elements. In this situation it is suggested that the selection is asked for again after he update.

Specified by:

updateElement in interface org.eclipse.jface.viewers.ILazyContentProvider

Parameters:

index - The index that is being updated in the table.
